HomePlug's digital entertainment technology provides high-quality networking over existing wiring within the home to any device with an Ethernet port or even to extend the range of a Wi-Fi router. The HomePlug AV2 specification is based on more than a decade of real-world experience and extensive field tests conducted by the alliance's AV Technical Working Group validating in-home coverage and performance across five countries with wide variances in home construction. HomePlug AV2 technology supports gigabit-class broadband speeds, making it well suited for Internet video, multi-room IPTV, online gaming, HD audio and other high demand networking uses, particularly when using multiple HD devices simultaneously.

Key features include a Gigabit-class PHY Rate (physical interface rate), support for MIMO PHY (multiple-input and multiple-output), whole home coverage with inherent repeater functionality and interoperability with HomePlug AV and HomePlug Green PHY devices. The new standard also has several power modes: active, standby and idle.
